To all whom it may concern-.-

Be it known that I, JOSEPH AsKrNs, of Lima, in the county of Allen and State of Ohio, haveinvented certain new and useful ImprovementsiirRadiators; and Ido hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention is an improvement in radiators for steam-heating, the obj eet being to provide vertical air-tubes extending through the steam-tubes, by means of which the air in the inner tubes is heated and caused to rise, thereby causingacontinuous air-currentup through these tubes.

A further object is to divide the steam-spaces between the inner and outer tubes by metal diaphragms that ext-end also down through the steam-chamber below, dividing it into compartments, so that the steam in passing from one compartment to the next must pass upon one side of the diaphragm to near the top of the steam-tubes, and down on thc opposite side, and by means of which a constant circulation of steam is had through all parts of the radiator-,and the air is expelled from thesteampipes by the direct pressure of the steam.

A. further object is to provide an air-chamber under the ai r-pipe provided with an airtube leading outside of the building7 by means of which pure air may be introduced tothe air-tube and heated and discharged into the room.

Vith these objects in view my invention consists in certain features of construction and in combination of parts, hereinafter described, and pointed out-in the claims.

In the accompanying drawings Figure 1 is an elevation of the tubes and a transverse vertical section of the base of the radiator. Fig. 2 is a horizontal section through one of the steam-tubes and the inclosed air-tube and diaphragm. Fig. 3 is a plan view of the bottom. plate of the base, the walls and bars of the base and the diaphragm being in section. Fig. 4L is an elevation of the base with a portion broken away to show the removable bottom, valve, and air-duct. Fig. 5 is a transverse vertical section of a modification of the removable bottom, and Fig. G is aviewin trans- Averse section throughthe pipes and base.

A represents a hollow base inclosing asteamchamber, the upper casing, a, of which is pro-I tight j oint therewith. The underside ofthe cap may be lined with soft metal or other packingsuch, for instance, as a copper gasket-to insure a tight joint. Before the caps are screwed on, the diaphragms E are inserted between the tubes B andO. metal bent, as shown in Fig. 2, and when in position between the tubes the edges engage opposite sides of the steam-tubes and the eentral. portionpresses against the air-tube, thus dividing the steam-space between those tubes into two parts. These diaphragms extend from near the top of the`steam-tubes'to the bottom of the steam-chai'nber A in the base. On the inside ofthe base, and integral therewith, are the ribs arranged opposite the tubes in a lateral direetin, and their inner edges flush with the inside of the steam-pipes B. Bars ci extend from top to bottom of the steam-chamber and integral therewith, and the sides thereof` are flush with the inside of the steampipe. The edges of the diaphragms E engage on one side the edge of one of the ribs and on the other side the edge of the bars as, so that the ribs, bars, and diaphragms form a partition-wall across the steam-chamber and divide it into compartments. The induction and eduction pipes enter the base at opposite ends in the usual manner. Vhen the steam is admitted, it fills the first compartment, but must pass up one side of the diaphragms and down the other side to enter the next compartment, and so on through the radiaton The air in ssl These consist of thin strips of 7o the radiator has therefore no place for lodgment, but is forced out in advance ofthe steam, and the radiator will become heated in every IOC) part in a few moments after steam is rst admitted. The lower corners of the diaphragms may be clipped, as shown' at e, to provide a means of escape for the condensed water from one compartment to another toward the eduction-pipe. These openings e are quite small and usually more or less lled with water, so that but a trifiing amount of steam can pass through them, and hence do not interfere with the general passage of steam up and down the pipes, as aforesaid. A. bottom, F, preferably detachable, is secured below, inelosing an airchamber, F', from which air is supplied to the air-tubes C. An uir-pipe, G, leads to the out- Side of the building, through which pure air may be admitted to supply the pipes C. An opening, f, is arranged near the mouth of the pipe G, and a damper, H, is provided with the rod li, attached, by means of which the damper may be moved so as to close the mouth of the pipe G or the opening f, according as it is desired to admit air from the outside of the building or f rom the room to supply the tubes C. The base of the heater may have a pendent flange, to which the bottom F may be attached, or the part F may be dish-shaped, as shown in Figs. 5 and 6. The part F may be cast integral with the base of the heater, but l prefer to make it detachable, so that in case the radiator is to be used when the part F and attachments are not required they may be omitted, and thus save expense.

I am aware that it is old to provide radiatortubes with diaphragms arranged longitudinally therein, whereby a. circulation of steam is created through said tubes. l am also aware that it is old to divide the base of a radiator' in a series of sections so connected by pipes or tubes that the steam after it leaves one section 'is forced to pass through the pipes connecting said section with another section before it can enter said latter section.

That lf claim isi.. In a radiator, the combination, with a base having a steam-chamber and an air-chiunber, of air pipes or tubes secured to the lloor of the steam-chamber and comm unicating with the air-chamber, asteam-pipe surrounding each air-pipe and secured to thereof or upper plate of the steam-chamber and connnunieating with said chamber, diaphragms located within the spaces between the steam and air pipes, and extending from near the top of said pipes to the bottom of the steam'chamber, and ribs or walls located within the steaxnchainber, the said ribs or walls and the diaphragms dividing the steam-chamber into a series o'
